SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 241,848, dated May 24, 1881.

Application filed January 10, 1880.

To all whom it may concern Be it known that I, REUBEN ELLWOOD, residing at Sycamore, in the county of De Kalb and State of Illinois, and a citizen of the United States, have invented new and useful Improvements in Sulky-Plows, of which the following is a-full description, reference being had to the accompanying drawings, in which- Figure l is a top or plan view with the seat removed and the rear end of the plow-beam with the plow broken away; Fig. 2, a section on line was of Fig. 1, showing also the seat and the plow in position Figs. 3,4, 5, 6, 7, details.

This invention relates to that class of sulkyplows in which an arch or frame mounted on wheels carries a crank, from which is suspended, byapivotal connection, the plow-beam, with its plow, the ends of the crank being pivoted to the sides of the arch or frame, which frame also has a drivers seat mounted thereon, and carries the tongue and the levers for leveling the plow and adjusting the depth at which it runs in the ground; and in order to perform its work in a successful and efficient manner a sulky-plow of this description should have the plow-beam suspended from its crank, so as to allow perfect freedom of movement vertically for adjusting purposes, and a movement laterally on the crank, to adapt the same crank to receive plows of different widths, and the connection must have such relation to the plow beam and crank as that the movements will not cause locking or binding and render the connection inoperative. The plow should have such support that it will be held firmly, and yet allow the wheels to conform to the irregularity of the surface ofthe ground, as may be desired for the nature of the-plowing. 1

The object of this invention is to attain the several results above referred to; and the invention consists, essentially, in a novel connection for the forward end of the plow-beam; also a novel connection between the plowcrank and the plow-beam, all of which will be fully hereinafter described, and specifically pointed out in the claims.

In the drawings, A represents the tongue; B, the tonguesupport; O, the arch or frame;

O, the forward extensions or arms; D, the rod for the forward support; E, the clevis; F, the

plow-beam; G, the plow; H, the plow-crank; I, the depth-adjusting lever; l, the rack for the lever I; J, the furrow-wheel; J, the landwheel; K, the furrow-wheel spindle; K, the land-wheel spindle; L, the lever for leveling the plow; L, the connecting-link; M, the rack for the lever L; N, the seat-support; O, the seat.

a is the swinging loop or yoke; a, the notches in a; b, the sliding catch; 12, the engaging-point on b,- c, the ears for attaching the rear end of the tongue; (I, the hangers or bars connecting the forward end of B with the extension 0 e, the collars for holding the clevis in position on D; f, the series of holes in the clevis; g, the socket; g, the extension or arm h, the loop or yoke on the plow-beam; z, the set-collars for g j, the sliding catch or pawl on the lever L; k, the connecting-link; l, the lever for operating the sliding catch j to engage or disengage the lever L.

The tongue A is of the ordinary construction, and is pivoted at its rear end between the ears 0, located on the tongue-support B, which support is firmly attached to the furrow side of the frame or arch O, and, as shown, projects both to the front and rear, its front end being connected by the bars or hangers d to the arm or extension .0 for strengthening purposes. The loop or yoke (t is located on the support B, near its forward end, and is pivoted at its lower end to each side of the support, so that it can swing, and its arms extend up each side of the tongue a distance to allow the tongue to have considerable play in the loop or stirrup. The rearedge of the inner arm of the loop a has a series of notches, a, any one of which, as desired, can be engaged with the point D of the slide 1), which slide is located on the inner side of the tongue, at the rear of the loop a, and is held in position by screws or bolts, which pass through slots in the slide and enter the tongue, the slots allowing the slide to be moved. By means of this loop or stirrup a and the sliding catch b the forward end of the tongue can be raised or lowered and held in any desired position, so as to adjust it in relation to the plow, to cause the plow to be held firmly in the ground and to its work and at the same time the relationJoetwcen the team and the end of the tongue will not be changed.

The frame or arch C may be made of a single piece, bent so as to form the horizontal portion and vertical ends, or in any other suitable manner, and the arms orextensions C may be in a single piece with the frame or arch, or may be independent pieces rigidly secured to the vertical portions of the frame, and projecting forward so as to bring their outer ends in proper relation with the clevis to enable it to be pivoted on the front cross-rod, which rod D is firmly secured in the outer ends of the arms 0.

The clevisE is provided with a suitable bearing to receive the rod D, which bearing is located near its lower edge and back of the openings f for the double-tree clevis. As shown, this clevis consists of two similar plates firmly attached one to each side of the plow-beam, with sideproieeting hubs or bosses through which is a suitable opening for the passage of the rod D. On the rod D, on each side of the clevis, are set-collars e, which can be brought in contact with the hubs or bosses on the clevis and prevent any lateral movement of the plowbeam on the rod, but allowing the forward end of the beam to turn on the rod as a pivot.

The plow-beam F may be of any of the wellknown forms of construction, and carries an ordinary plow, G, attached to its rear end in the usual manner. The front end of this beam is pivoted to the rod 1) by means of the clevis E, so that it can rock or turn on the rod for the purpose of adjusting the plow; but when the plow is locked this connection at the front end of the beam becomes rigid with the frame, and theplow will be held firmly in all directions, except the entire frame be moved, and thereby irregular movements of the plow to any great extent will be prevented, and the plowing will be more uniform in character and depth.

Theplow-crank 11 may be formed in the usual manner, and, as shown, is pivoted at one end to a stud or pin on the side of the frame or arch, and has its other end passing through the otherlside of the frame or arch and forming the pivot at that end. The plow-beam is suspended from the central portion of this crank H by a socket, 9, located in the crank, which socket has an arm or projection, g, extending out therefrom a sufilcient distance to enter a loop, h, which is pivoted to the plowbeam, and in which the arm or extension 9 is pivoted, so that the connection between the plow beam and crank has three pivotal points-- the socket on the crank, the arm g in the loop or stirrup h, and the loop or stirrup to the plow beam; and the arrangement and location of these pivotal points, one to the other and to the plow beam and crank, are such that, no matter to what position the plow-crank and the plow beam may be adjusted,the pivots cannot bebrought into line so as to lock the beam in both directions at the same time by the lever, and at the same time the plow beam and crank have the necessary freedom of movement required for adjusting purposes.

By means of the socket g, with its arm or extension g, and the stirrup or loop h, a connection between the plow beam and crank is provided, which is cheap, simple, efficient, and well adapted for the purpose for which it is designed, and anylateral movementof the socket on the crank is prevented by the set-collars 1', one on each side of the socket, and these collars also permit of a lateral adjustment of the plow-beam on the crank, so that the same beam may be used for different widths of plow and maintain the proper relation to the furrowwheel,as by loosening the set-collars the plowbeam can be moved toward or from the furrow-wheel, as required, and when properly adjusted can be held by bringing the set-collars in contact with the socket g and tightening them.

The crank and plow-beam are adjusted for work by the lever I, the lower end of which is attached to the projecting end of the crank H. This lever 1 may be of any form of construction suitable for the purpose of raising and lowering the crank, and, as shown, carries a sliding pawl for engaging with the notches of a rack, I, attached at its ends to the support B, and locking the lever in any desired position, the pawl being operated by a connecting rod or link and a bell-lever in the usual manner. By means of this lever I the crank 11 can be raised or lowered, so as to adjust the plow, and when adjusted the limited vertical play allowed by the connection g, g, and h, when the plow is in the ground, leaves the plow to run independent without being affected by the inequalities on the surface of the ground over which the wheels pass, the lever in this instance being brought to a position that leaves the connection between the crank and beam free to play either up or down, so that when the wheels pass over an obstruction the bail or crank rises with the wheel without disturbing the position of the plow, and when the Wheels drop into a depression the bail or crank drops also, without disturbing the position of the plow.

When it is desired to prevent the plow from rising, except the entire machine is raised,the lever I is carried forward to a position that will lock the beam and crank by raising the crank to the extent of the upward movement of the connection and prevent any upward movement of the crank independent of the beam, butleaving a free downward movement, so that the plow will be carried on the wheels, and not ride the plow when the wheels drop. By this connection the plow can be locked in one direction, as desired, or can be left to run independent by simpl ychan gin g the position of the lever I.

The furrow-wheel J and its spindle K and the land-wheel J and its spindle K may be of any of the well-known forms of construction, the spindle K, as shown, being attached to a head, so that by means of a link, L, and lever L, the plow can be leveled in the usual manner, the lever L carrying a sliding pawl, j, operated by a bell-lever, 1, through the rod or link 7a, which pawl engages with notches in a segmental rack rigidly attached to the frame or arch andholds the lever L in any desired position.

A drivers seat, 0, mounted on a spring-bar, N, is to be provided.

The connection g g h leaves the plow to run independent in so far as relates to vertical movements of the crank in either direction, prevents the plow from riding when the wheel drops, allows the wheel to conform to the nature of the ground without affecting the depth of the plowing, removes the weight from the beam, and produces a much lighter and easier draft.

What 1 claim as new, and desire to secure by Letters Patent, is

1. In a sulky-plow, the arched frame 0, provided with the forwardly-projeetin g extensions 0, and carrying a crank, from which the plowbeam is suspended, in combination with the connection for the forward end of the plowbeam, formed by passing the cross-rod through the clevis and connecting its ends to the forward extensions of the arched frame, substantially as described,'whereby when the plow is locked the forward connection becomes rigid, substantially as described.

2. In combination withthe plow-crank and plow-beam, the socket 9, arranged on the crank, and provided with the rearward extension 9 and the stirrup h, pivoted at its ends to the rearward extension 9 and to the plow-beam, respectively, substantially as described, whereby the plow-beam can swing vertically and forwardly and rearwardly, as set forth.
